- use c++ to Implement a city database using a BST to store the database records. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x- and y-coordinates. The BST should be organized by city name. Your database should allow records to be inserted, deleted by name or coordinate, and searched by name or coordinate. Another operation that should be supported is to print all records within a given distance of a specified point. Collect running-time statistics for each operation. Which operations can be implemented reasonably efficiently (i.e., in O(log n) time in the average case) using a BST? Can the database system be made more efficiently by using one or more additional BSTs to organize the records by location?use c++ to Implement a city database using a BST to store the database records. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x- and y-coordinates. The BST should be organized by city name. Your database should allow records to be inserted, deleted by name or coordinate, and searched by name or coordinate. Another operation that should be supported is to print all records within a given distance of a specified point. Use following two classes: struct city { /* add the city attributes and pointers to left and right child nodes*/ } class CityDB { /* create a BST for a City Database here in this class */ } Note: The distance formula is , where x1,y1 are coordinates of city 1 and x2, y2 are coordinates of city 2.Using c language Implement M.A.S.H.

Use…A very long line: What data structure or structures would you use to maintain a very long queue of records, each having an id (some sort of string). You need to be able to find the first item in O(1) time, add to the end in O(1), and remove items in O(1) time, given some id (not index), from anywhere in the line. Additionally, you need to be able to find an item in line in O(1) time and see what items are near it (in front of or in back of) in O(1), possibly more (each is O(1) time). Explain what is stored in each Data Structure (“record (with id possibly)”, “pointers to ______”).Write a C++ program to implement a bank queue, using Singly-Linked List, which will allow the branch manager to perform the following functions: Enqueue a new Customer Serve Customer Display Queue Time to Serve Following details should be displayed against each record: Queue ID, Name, Service Required, No. in Queue
- Please answer it in C ++ Follow all code styling and submission instructions as outlined for previous labs. Declare and implement a BSTNode ADT with a data attribute and two pointer attributes, one for the left child and the other for the right child. Implement the usual getters/setters for these attributes. Declare and implement a BST as a link-based ADT whose data will be Dollar objects - the data will be inserted based on the actual money value of your Dollar objects as a combination of the whole value and fractional value attributes. For the BST, implement the four traversal methods as well as methods for the usual search, insert, delete, print, count, isEmpty, empty operations and any other needed. Your pgm will use the following 20 Dollar objects to be created in the exact order in your main to seed the tree: $57.12 $23.44 $87.43 $68.99 $111.22 $44.55 $77.77 $18.36 $543.21 $20.21 $345.67 $36.18 $48.48 $101.00 $11.00 $21.00 $51.00 $1.00 $251.00 $151.00 Also, create an…An Abstract Data Type (ADT) specification does not indicate how to store the data or how to implement the operations.

- Computer Science It is needed to design a database system for a pharmacy. The pharmacy contains many different items. Items may be products or medicines. Medicines are classified into different types either bills, injection, capsule or drugs or any combination of them. An item must be supplied by only one supplier. A supplier may supply many type of items. A customer may order many items. The pharmacy has a unique name, address and more than one telephone. The doctor can prescribe one or many medication, injections can not be bought without a doctor prescription. You are requested to draw the EERD diagram for the described system You are required to write down any assumptions made from your side You should add the attributes and cardinality for all the entities You are required to model the EERD into relational modelTrue or False: Can indexing be viewed abstractly as a process to determine if an element with a particular value is a member of a particular set? Is the more common view of indexing an attempt to find the record within a collection of records that has a particular key value, or those records in a collection whose key values meet some criterion such as falling within a range of values? Thus, can we say indexing in data structure refers to the process of finding location of an element in a list? Give an example.What considerations arise when handling "backward compatibility" in serialized data structures?
